Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle.Click to see full answer. In this manner, how does the mitotic spindle work?The mitotic spindle is a structure composed of microtubules which segregates chromosomes into the daughter cells during mitosis. A kinetochore microtubule is a microtubule which attaches to the kinetochore and positions the chromosomes during mitosis.Furthermore, what is a mitotic spindle in biology? The mitotic spindle is the macromolecular machine that segregates chromosomes to two daughter cells during mitosis. The major structural elements of the spindle are microtubule polymers, whose intrinsic polarity and dynamic properties are critical for bipolar spindle organization and function. Also know, what builds the mitotic spindle? The centrosome determines the shape of the cell as well as the mitotic spindle apparatus. In eukaryotic cells, polymerization of microtubules from alpha and beta tubulin is initiated at the centrosome to form the mitotic spindle and the structure for cytokinesis.What is a spindle assembly?A central goal of cell division in eukaryotes is to separate two identical copies of the DNA and evenly distribute them to the daughter cells. This task is performed by microtubules that assemble into a spindle-shaped apparatus around the chromosomes.
